, Claims. 1

The present invention relates to hammer guards for firearms and it consists in the combiposition and Whose forward end engages the conventional rearwardly extending lip of the recess wherein the firing pin lies. A spring-pressed detent is carried by the hammer holder and is adapted to engage the shank of the hammer when in locked position. Means isprovided forholding the detent in locked position when theguard is in locked condition. Means is provided for quickly and easily assembling and disassembling the'guard upon a revolver or the like and means is alsoprovided for locking with a key all of the attendant parts of the device when the-same is in position upon a firearm. 7

It is accordingly an object of the invention to provide a device of the character set forth which is simple in construction and operation and yet effective and efiicient in use.

Another object of the invention is th provision of novel means for holding the handle-of avfirearm in cocked position against accidental movement toward uncooked positions.

Another object of the invention is the provision of-novel latching means in-a device of the character set forth.

Another object of the invention is the provision of novel locking means for the aforesaidlatohing means. 7

Other and further objects of the invention will become apparent from a reading of the following specification taken in conjunction with the drawing,'in which:

Figure l is a side elevational view of an embodiment of the invention shown in closed'and locked position upon a revolver,

Figure 2 is a view similar to Figure 1 butshowing the device forming the present invention.

Figure '7 :is an enlarged sectional view along line l-"l of Figure 5.

Referring more particularly to the drawing, there isshown therein arevolver Hi provided with 'a conventional hammer having a head l, a shank 'lz anda thumb piece l3. There is also shown a firing pin id withina-recess l5 which is provided with a lip H3.

The device forming the'present inventionconsists of a rounded hood-like body i'lhaving an open bottom formed generally to the contour of the upper rear portion'of the revolver Ill and having an opening *I 8 forwardly therein.

A hammer holder 19 ispivotally mounted upon a transversely extending pin 26 which is mounted in the forward end of theiguard El and the holder [9 is provided with ahammer holding portion 2! and at'its rear end-which portion is adapted to engage the head I! of the hammer and at its forward end is provided with a hook-like. nose 22 which extends through the opening 18. A slot 23 is formed in .the forward end of the member 22. The hammer holder 2| i provided with a forwardly extending integrall formed extension 24 having a downwardly and rearwardly extending recess 25in which is reciprocally mounted a detent 26 having a transversely extending opening 2! therein and provided with a spring '28 which tends to normally urge the detent 26 out-- wardly of the recess 25.

The hood or cover I! has affixed therein a downwardly extending arcuate detent holder 29 Whose arc is spaced upon the .pin 20 as a center and which'extends through an arcuate opening 30 formed in the holder 2|. The hammer holder 2| isprovided upon each side with a recess 3! in which'is slidably mounted a detent 32 and a compresion spring '33 for normally urging the detent 32 toward an outward position and the cover I! is provided upon either side with a reoiprocally mounted pin 34 having head 35 within a recess 36 formed on the inner face of the cover I! and with an operating handle 3'! at its outer end. A compression spring 38 is interposed between the handle 3! and a collar 39 formed intgerally with the outer side of the cover A look member 40 of generally diamond shape is provided with integrally formed outwardly extending lips 4| and-is pivotally mountedupon a pin 42 affixed to one'side of the cover il. At either side of the pin 42 there is provided a recess-in the outer side of the cover I! in each of taken which recesses is slidably mounted a detent 43 and a compression spring 44 for normally urging the detent 43 outwardly of the cover IT. The lock member 40 is provided with a pair of openings 45 for the reception of a key 46 and there is also provided in the cover I! a pair of detents 41 similar to the detents 43 but mounted at ninety degree intervals to the latter.

In operation, it will be apparent that in order to place the device in position upon the firearm H], the lip I6 is first inserted into the slot 23 as particularly shown in Figure 3 of the drawing. Thereupon the device is swung downwardly and the detent 26 is forced inwardly into the recess by the base of the hammer head ll and will slide thereacross until it is again freed for outward movement whereupon it will engage the shank l2 of the hammer as shown in Figure 2 of the drawing. During this operation the handles 31 have been forced inwardly of the device by means of the thumb and one of the fingers of the operator. Upon the release of the handles 31, the detents 32 will engage in the recesses 36 and the member 29 will'pass through the opening and thence through the opening 21 in the detent 26 thus effectively latching the hammer holder in position against the base of the hammer II. For all ordinary purposes the hammer is now locked against any untoward use. However, at this time the device may be quickly removed from the revolver Ill by merely pressing inwardly the handle 31 thus causing the detents 32 to move inwardly in the recesses SI and allowing the cover to be swung outwardly thereby moving the member 29 from the recess 2'! in the detent 26 and thus allowing the hammer holder l9 to pivot outwardly of the cover I7 and thereby allowing the detent 26 to move inwardly of the recess 25 and thus slide over the base of the hammer thereby permitting the removal of the device from the handle.

Again, however, if it is desired to lock the device in position when it is in latched condition, the key 46 is inserted into the openings 45 thereby pressing inwardly the detents 41 and allowing the lock member to be turned by the key to a horizontal position as viewed in Figure 5 whereupon one of the lips 4| will engage therefor beneath its adjacent handle 3! thus effectively preventing the movement of the pin 34 inwardly to thereby permit the inward movement of one of the detents 32. When in the position thus described detents 42 will engage in the openings '45 upon the removal of the key 46 thus preventing any unauthorized use of the hammer of the pistol. 7

While but one form of the invention has been shown and described herein, it will be readily apparent to those skilled in the art that many minor modifications may be made without departing from the spirit of the invention or the scopeof the appended claims.
